Functions Supported for Code Acceleration or C Code Generation
The following general limitations apply to the use of Fixed-Point Designer™ functions in generated code, with
quantizerobjects are not supported.
Word lengths greater than 128 bits are not supported.
You cannot change the
numerictypeof a given
fivariable after that variable has been created.
booleanvalue of the
DataTypeproperties are not supported.
SumModeproperty settings other than
CastBeforeSumproperty must be set to
You can use parallel for (
parfor) loops in code compiled with
fiaccel, but those loops are treated like regular
When you compile code containing
fiobjects with nontrivial slope and bias scaling, you may see different results in generated code than you achieve by running the same code in MATLAB®.
To view a list of the Fixed-Point Designer functions that are supported for code acceleration or C/C++ code generation, refer to the Fixed-Point Designer category of these tables:
In these tables, a icon before the name of a function indicates that there are specific usage notes and limitations related to code acceleration or code generation for that function. To view these usage notes and limitations, in the corresponding reference page, scroll down to the Extended Capabilities section at the bottom and expand the C/C++ Code Generation section.
